Elon Musk may be the world’s most eco-loving, planet-hugging billionaire, but that isn’t enough for some of his shareholders – they are demanding he makes his Tesla cars “cruelty free“.

The unusual request was made at Tesla’s AGM this week by two shareholders who demanded that they phase out the use of leather in their cars by 2019:

“Tesla has two choices. Tesla can continue to fill cars with the skins of sentient beings that suffer unspeakable horror while adding massive amounts of greenhouse gas into the air. According to the UN and other sources, this is the fundamental truth of using animal skins or Tesla can adopt one of the many faux leather materials used by Mercedes Benz, Lexus, BMW, Infiniti and others that are cruelty free, have wonderful reviews, last the long time, come in multiple colors and have — and involve far less greenhouse gases.”
